On December 29, 1911, after the revolution of 1911, 17 provincial representatives who had recovered elected Sun Yat-sen as the interim president of the Republic of China in Nanjing. On January 3, 1912, the government of the Republic of China was founded and the Qing Dynasty was destroyed. The feudal autocracy which lasted for more than 2000 years in China ended. When the Republic of China was founded, because the currency system had not yet been established, except for the silver coins of Dahan in Sichuan and Zhonghua Yuanbao in Fujian, most of the major mints still used the steel mould of the former Qing Dynasty to cast silver coins for circulation. Due to the confusion of the currency system, Chen Jintao, the finance minister of the interim government, submitted a letter to Sun Yat-sen, the president of the Republic of China, on March 11, the first year of the Republic of China, calling for 10 million yuan of commemorative silver coins for rectification. The design adopts the portrait of Sun Yat-sen, the great president, and later the general silver coin changes the pattern. Sun Yat-sen ordered the Ministry of finance to write, agreed to drum cast commemorative coins, and ordered the rest of the general silver coins to have new patterns, "in the middle, a model of five grains should be drawn, taking the meaning of the rich, the old and the people, and following the rules of urging the farmers to do business", ordered the Ministry of finance to quickly make new patterns, and ordered the mints of all provinces to drum cast according to the patterns. Soon after, the Ministry of Finance issued a new model to Jiangnan (Nanjing), Hubei, Guangdong and other mints, which was the origin of "the founding commemorative coins of Sun Yat Sen of the Republic of China".

[collection name]: one yuan of commemorative coins of the founding of the Republic of China

When the Republic of China was founded, because the currency system had not yet been established, except for the silver coins of Dahan in Sichuan and Zhonghua Yuanbao in Fujian, most of the major mints still used the steel mould of the former Qing Dynasty to cast silver coins for circulation. Due to the confusion of the currency system, Chen Jintao, the finance minister of the interim government, submitted a letter to Sun Yat-sen, the president of the Republic of China, on March 11, the first year of the Republic of China, calling for 10 million yuan of commemorative silver coins for rectification. The design adopts the portrait of Sun Yat-sen, the great president, and later the general silver coin changes the pattern. Sun Yat-sen ordered the Ministry of finance to write, agreed to drum cast commemorative coins, and ordered the rest of the general silver coins to have new patterns, "in the middle, a model of five grains should be drawn, taking the meaning of the rich, the old and the people, and following the rules of urging the farmers to do business", ordered the Ministry of finance to quickly make new patterns, and ordered the mints of all provinces to drum cast according to the patterns. Soon after, the Ministry of Finance issued a new model to Jiangnan (Nanjing), Hubei, Guangdong and other mints, which was the origin of "the founding commemorative coins of Sun Yat Sen of the Republic of China".

In the center of the back is the Chinese clerical style "Yiyuan" and Jiahe, with the edge of the English "Republic of China" and "Yiyuan", with five pointed stars (later changed to hexagon star). Straight edge teeth, commonly known as "small head". As the currency of the Republic of China, it is widely circulated and has a large number. The silver dollar, the commemorative coin of the founding of Sun Xiang in the Republic of China, was not all minted in the first year of the Republic of China. In the 16th and 17th years of the Republic of China, the mints of Nanjing and Tianjin were all minted, but all of them adopted the "commemorative coins of the founding of the Republic of China". The silver dollar, the commemorative coin of the founding of Sun Xiang in the Republic of China, is not very good at English because of different foundries, different casting times, and the Engravers' English level. Except for the main patterns on the front and back, there are variations in the details of flower decorations and English letters, especially the errors in English letters. This resulted in a variety of types of the coin. There are two main types that have been handed down widely: the pentagram and the hexagon

About Pentagram layout. From the five pointed star's azimuth setting, the flower decoration's subtle difference distinguishes: 1. The next five pointed star version. In the first year of the Republic of China (1912 A.D.), Nanjing mint, according to the order of the Ministry of finance, first struck the commemorative coins of the founding of the Republic of China. On the front of the silver dollar, Sun Yat Sen's side portrait is engraved in the center, and on the outside, there are two circles (inner circle, outer bead circle). On the edge, there are four characters of Chinese official script "Republic of China" and five characters of Chinese official script "Founding commemorative coins", with long branches and flowers on the left and right. In the center of the back is engraved the Chinese official script "one circle" and Jiahe; in the outer double circle (inner circle, outer bead circle), on the edge is engraved the English "therepublicofchina" (Republic of China), and under is engraved the English "onedollar" (one yuan), with five stars at the bottom left and right. So it's called the next pentagram. The characteristics of the coin are: the five pointed star is in the lower position, and the left and right two five pointed stars are in the right position. Pentagram is close to English letters. There are no wrong versions of English letters. After Yuan Shikai stole the president, the coin was stopped. Because of the short time, it was rarely used, especially precious. 2. Upper pentagram. This coin is also a rare one. The coin was struck by Tianjin Mint in the 17th year of the Republic of China (1928). The obverse and the back of the silver dollar are roughly the same as those of the first grade, with five pointed stars at the top left and right. So it's called the pentagram. The characteristics of the coin are: the pentagram is in the upper position, the left side of the pentagram is relatively straight, and the right side is relatively inward inclined. Pentagram is far away from English letters. There are no wrong versions of English letters.

About the hexagon layout. In the 14th year of the Republic of China, the national government was established in Guangzhou, moved to Wuhan in the 15th year of the Republic of China, and established its capital in Nanjing in the 16th year of the Republic of China (1927 A.D.). In order to commemorate the great achievements of Sun Yat-sen, all the coins of the central government were made with the image of the father of the state. In the 16th and 17th years of the Republic of China, the mints of Nanjing and Tianjin recast the commemorative coins of the founding of the Republic of China. The front and back of the silver dollar are basically the same as the former, while the top left and right are hexagons. It weighs 27g. As the obverse and reverse of the coin are relatively regular, there is no error in Chinese and English, and there is also a hexagon star, so it is called the ordinary hexagon star version. Due to the small circulation at that time, the current amount of life is less, which has a high collection value.
